Yuma, AZ

Yuma sits in the Colorado Desert where Arizona meets California and Mexico, with flat terrain and minimal elevation change making it ideal for speed work and time trials year-round. Winter running (November–February) dominates the local scene since summer heat regularly exceeds 45°C; the Castle Dome Mines Road and Imperial Dam routes offer long, straight miles across open desert. Cyclists face the same heat constraint but find consistent tailwinds and predictable conditions for base-building during cooler months, with loops along the All-American Canal providing flat, shaded riding.
